DESCRIPTION

Mail::Sendmail contains mainly &sendmail, which takes a hash with the message to send and sends it. It is intended to be very easy to setup and use. See also "FEATURES" below.

INSTALLATION

Best

perl -MCPAN -e "install Mail::Sendmail"

Traditional

perl Makefile.PL
make
make test
make install

Manual

Copy Sendmail.pm to Mail/ in your Perl lib directory.

(eg. c:\Perl\site\lib\Mail\
or /usr/lib/perl5/site_perl/Mail/
or whatever it is on your system.
They are listed when you type C< perl -V >)

ActivePerl's PPM

ppm install --location=http://alma.ch/perl/ppm Mail-Sendmail

But this way you don't get a chance to have a look at other files (Changes, Todo, test.pl, ...).

At the top of Sendmail.pm, set your default SMTP server(s), unless you specify it with each message, or want to use the default (localhost).

Install MIME::QuotedPrint. This is not required but strongly recommended.

FEATURES

Automatic time zone detection, Date: header, MIME quoted-printable encoding (if MIME::QuotedPrint installed), all of which can be overridden.

Bcc: and Cc: support.

Allows real names in From:, To: and Cc: fields

Doesn't send an X-Mailer: header (unless you do), and allows you to send any header(s) you want.

Configurable retries and use of alternate servers if your mail server is down

Good plain text error reporting

LIMITATIONS

Headers are not encoded, even if they have accented characters.

No suport for the SMTP AUTH extension.

Since the whole message is in memory, it's not suitable for sending very big attached files.

The SMTP server has to be set manually in Sendmail.pm or in your script, unless you have a mail server on localhost.

Doesn't work on OpenVMS, I was told. Cannot test this myself.

CONFIGURATION

Default SMTP server(s)

This is probably all you want to configure. It is usually done through $mailcfg{smtp}, which you can edit at the top of the Sendmail.pm file. This is a reference to a list of SMTP servers. You can also set it from your script:

unshift @{$Mail::Sendmail::mailcfg{'smtp'}} , 'my.mail.server';

Alternatively, you can specify the server in the %mail hash you send from your script, which will do the same thing:

$mail{smtp} = 'my.mail.server';

A future version will (hopefully) try to set useful defaults for you during the Makefile.PL.

If you wish to use an envelope sender address different than the From: address, set $mail{Sender} in your %mail hash.

The following are not exported by default, but you can still access them with their full name, or request their export on the use line like in: use Mail::Sendmail qw(sendmail $address_rx time_to_date);

Mail::Sendmail::time_to_date()

$Mail::Sendmail::error

When you don't run with the -w flag, the module sends no errors to STDERR, but puts anything it has to complain about in here. You should probably always check if it says something.

$Mail::Sendmail::log

A summary that you could write to a log file after each send

$Mail::Sendmail::address_rx

A handy regex to recognize e-mail addresses.

A correct regex for valid e-mail addresses was written by one of the judges in the obfuscated Perl contest... :-) It is quite big. This one is an attempt to a reasonable compromise, and should accept all real-world internet style addresses. The domain part is required and comments or characters that would need to be quoted are not supported.

%Mail::Sendmail::mailcfg

This hash contains all configuration options. You normally edit it once (if ever) in Sendmail.pm and forget about it, but you could also access it from your scripts. For readability, I'll assume you have imported it (with something like use Mail::Sendmail qw(sendmail %mailcfg)).

The keys are not case-sensitive: they are all converted to lowercase before use. Writing $mailcfg{Port} = 2525; is OK: the default $mailcfg{port} (25) will be deleted and replaced with your new value of 2525.

$mailcfg{smtp}

$mailcfg{smtp} = [qw(localhost my.other.mail.server)];

This is a reference to a list of smtp servers, so if your main server is down, the module tries the next one. If one of your servers uses a special port, add it to the server name with a colon in front, to override the default port (like in my.special.server:2525).

Default: localhost.

$mailcfg{from}

$mailcfg{from} = 'Mailing script me@mydomain.com';

From address used if you don't supply one in your script. Should not be of type 'user@localhost' since that may not be valid on the recipient's host.

Default: undefined.

$mailcfg{mime}

$mailcfg{mime} = 1;

Set this to 0 if you don't want any automatic MIME encoding. You normally don't need this, the module should 'Do the right thing' anyway.

Default: 1;

$mailcfg{retries}

$mailcfg{retries} = 1;

How many times should the connection to the same SMTP server be retried in case of a failure.

Default: 1;

$mailcfg{delay}

$mailcfg{delay} = 1;

Number of seconds to wait between retries. This delay also happens before trying the next server in the list, if the retries for the current server have been exhausted. For CGI scripts, you want few retries and short delays to return with a results page before the http connection times out. For unattended scripts, you may want to use many retries and long delays to have a good chance of your mail being sent even with temporary failures on your network.

Default: 1 (second);

$mailcfg{tz}

$mailcfg{tz} = '+0800';

Normally, your time zone is set automatically, from the difference between time() and gmtime(). This allows you to override automatic detection in cases where your system is confused (such as some Win32 systems in zones which do not use daylight savings time: see Microsoft KB article Q148681)

$Mail::Sendmail::VERSION

The package version number (you can not import this one)

Configuration variables from previous versions

The following global variables were used in version 0.74 for configuration. As from version 0.78_1, they are not supported anymore. Use the %mailcfg hash if you need to access the configuration from your scripts.

Now uses Sys::Hostname to get the hostname for HELO. (This may break the module on some very old Win32 Perls where Sys::Hostname was broken)

NOTES

MIME::QuotedPrint is used by default on every message if available. It allows reliable sending of accented characters, and also takes care of too long lines (which can happen in HTML mails). It is available in the MIME-Base64 package at http://www.perl.com/CPAN/modules/by-module/MIME/ or through PPM.

You can use this module freely. (Someone complained this is too vague. So, more precisely: do whatever you want with it, but be warned that terrible things will happen to you if you use it badly, like for sending spam, or ...?)

Thanks to the many users who sent me feedback, bug reports, suggestions, etc. And please excuse me if I forgot to answer your mail. I am not always reliabe in answering mail. I intend to set up a mailing list soon.
